Automobile calibration device

ABSTRACT

The present invention relates to the field of automobile maintenance and device calibration technologies, and discloses a clamping apparatus and an automobile calibration device. The clamping apparatus includes a fixing plate, a fixing block and a tension knob. The fixing block includes a fixing block body and a locking spring piece. The fixing block body is installed on the fixing plate. A receiving cavity is enclosed by the fixing block body and the fixing plate. The locking spring piece is located in the receiving cavity. The tension knob is installed on the fixing block body. The tension knob is capable of rotating relative to the fixing block body, to extend inside the receiving cavity and to abut against the locking spring piece. When a to-be clamped and calibrated apparatus is inserted in the receiving cavity, the tension knob may push the locking spring piece to abut against the to-be clamped and calibrated apparatus. Because the locking spring piece is in surface contact with the to-be clamped and calibrated apparatus, a friction between the locking spring piece and the to-be clamped and calibrated apparatus increases, so that the locking spring piece may firmly abut against the to-be clamped and calibrated apparatus.

This application is a continuation of International Patent Application No. PCT/CN2019/083597 filed on Apr. 22, 2019, which claims priority to Chinese Patent Application No. 201810362137.X filed on Apr. 20, 2018, both of which are incorporated by reference herein in their entireties.

BACKGROUND Technical Field

The present application relates to the field of automobile maintenance and device calibration technologies, and in particular, to an automobile calibration device having a clamping apparatus.

Related Art

In the field of automobile maintenance, for example, during calibration of an advanced driver assistant system (ADAS), a calibration apparatus needs to be installed on an automobile calibration device, to calibrate in-vehicle assistance driving components, such as a camera.

For different automobile models or different calibration requirements, different calibration apparatuses need to be changed frequently, and the calibration apparatuses need to be locked tightly and secured. Currently, common structures are locking by using a C-type snap ring and abutting tightly by rotating a screw. The two structures have the following defects:

1. The C-type snap ring may slip, and is inconvenient to be assembled due to a small gap during an assembly process.

2. In the manner of abutting tightly by using the screw, there is only one fulcrum used for securing, which easily leads to a location deviation. In addition, if the calibration apparatus is an appearance component, the surface of the appearance component is easily damaged.

The gear 242 and the knob portion 244 are respectively installed on two ends of the rod body 240. The gear 242 meshes with the rack gear 222. When the rod body 240 rotates relative to the sliding member body 210, the gear 242 drives the rack gear 222 to move horizontally, so that the supporting member 22 is driven to move horizontally relative to the sliding member 21. The knob portion 244 is located outside the sliding member body 210 and is configured to make it convenient for a user to hold and rotate the adjusting member 24.

It can be understood that, in some other embodiments, the installation positions of the adjusting member 24 and the rack gear 222 may be exchanged, that is, the adjusting member 24 may be installed on the supporting member body 220. The rack gear 222 is fixedly installed on the sliding member body 210 and the rack gear 222 is disposed in a horizontal direction.

In this embodiment, the linear slide rail 230 is disposed in a horizontal direction. The rack gear 222 is strip-shaped and disposed in a horizontal direction and includes a plurality of gear tooth disposed in a vertical direction. The gear 242 is a spur gear. These structures enable the supporting member 22 to be movable in a horizontal direction relative to the sliding member 21.

The rack gear 222 is strip-shaped and is disposed in the preset direction. Therefore, when the gear 242 rotates, the rack gear 222 may be driven to move in the preset direction, so that the supporting member 22 is movable in the preset direction relative to the sliding member 21.

In this embodiment, the gear 242 is a spur gear. The rack gear 222 includes a plurality of gear tooth disposed in a vertical direction. According to the cooperation between the gear 242 and the gear tooth of the rack gear 222, the supporting member 22 is horizontally movable relative to the sliding member 21 smoothly and precisely. It can be understood that, in some other embodiments, the gear 242 may be a helical gear. The rack gear 222 may include a plurality of gear tooth disposed in an inclined way. According to the cooperation between the gear 242 and the gear tooth of the rack gear 222, the supporting member 22 is horizontally movable relative to the sliding member 21 smoothly and precisely.

The elevating screw rod 31 passes through the threaded through hole 2120 and the elevating screw rod 31 mates with the threaded through hole 2120 by threads. When the elevating screw rod 31 rotates around the central axis thereof, the slider 212 may be driven to rise or fall, so as to drive the location adjusting apparatus 20, the clamping apparatus 40, the sliding apparatus 50 and the scale apparatus 60 to rise or fall. It should be noted that, according to the threaded mating of the elevating screw rod 31 and the threaded through hole 2120, in one aspect, the location adjusting apparatus 20 may rise and fall gently and stably. In another aspect, because the location adjusting apparatus 20 has a certain mass, the elevating screw rod 31 and the threaded through hole 2120 implement a self-locking function, to automatically prevent the location adjusting apparatus 20 from sliding downward.

It can be understood that, according to an actual situation, the transmission mechanism 31 is not limited to the elevating screw rod 31. In some other embodiments, the transmission mechanism 31 may further be a gear set, a belt pulley mechanism, a turbine and worm mechanism or a sprocket mechanism.

The motor 3200 is fixedly installed on an upper surface of the installation plate 1200. The motor 3200 is a stepping motor. It can be understood that, in some other embodiments, the motor 3200 may be another control motor such as a servo motor. The first timing pulley 3202 is located in the inspection port 1208. The first timing pulley 3202 is fixedly installed on a rotating shaft of the motor 3200 and the first timing pulley 3202 and the rotating shaft of the motor 3200 are coaxially disposed. One end of the elevating screw rod 31 passes through the second shaft base 312 and the inspection port 1208. The second timing pulley 3204 is located in the inspection port 1208. The second timing pulley 3204 is fixedly installed on the elevating screw rod 31 and the second timing pulley 3204 and the elevating screw rod 31 are coaxially disposed. The first timing pulley 3202 and the second timing pulley 3204 are spaced by a preset distance. When the motor 3200 rotates, the first timing pulley 3202 drives the second timing pulley 3204 to rotate by using the driving belt 3206, so that the elevating screw rod 31 rotates around the central axis thereof. When the motor 3200 rotates in a first rotational direction, the location adjusting apparatus 20 rises in a vertical direction relative to the bracket apparatus 10; and when the motor 3200 rotates in a second rotational direction, the location adjusting apparatus 20 falls in a vertical direction relative to the bracket apparatus 10. The first rotational direction and the second rotational direction are opposite.

The driving belt 3206 is sleeved on the first timing pulley 3202 and the second timing pulley 3204. When the first timing pulley 3202 rotates, the first timing pulley 3202 drives the second timing pulley 3204 to rotate by using the driving belt 3206. A peripheral surface of the first timing pulley 3202 and a peripheral surface of the second timing pulley 3204 are both provided with gear tooth. The driving belt 3206 includes an assembly surface 3207. The gear tooth of the first timing pulley 3202 and the gear tooth of the second timing pulley 3204 are both in contact with the assembly surface 3207. The assembly surface 3207 includes a gear teeth area 3208 and a non-gear teeth area 3209. The gear teeth area 3208 is provided with gear tooth. The gear teeth area 3208 may mesh and mate with the first timing pulley 3202 and the second timing pulley 3204. The non-gear teeth area 3209 may be in contact with and mate with the first timing pulley 3202 and the second timing pulley 3204. When the motor 3200 rotates and the gear teeth area 3208 meshes and mates with the first timing pulley 3202, or the gear teeth area 3208 meshes and mates with the second timing pulley 3204, the first timing pulley 3202 and the second timing pulley 3204 move synchronously, and a rate of the second timing pulley 3202 is a first preset rate value. When the motor 3200 rotates and the first timing pulley 3202 and the second timing pulley 3204 are only in contact with and mate with the non-gear teeth area 3209, due to factors such as slipping, the non-gear teeth area 3209 enables the first timing pulley 3202 and the second timing pulley 3204 to move asynchronously, and the rate of the second timing pulley 3202 is a second preset rate value. The first preset rate value is greater than the second preset rate value. It should be noted that, by dividing the gear teeth area 3208 and the non-gear teeth area 3209 on the assembly surface 3207, the rate of the second gear teeth 3204 is controlled while a rate of the first gear teeth 3202 remains unchanged, to achieve the purpose of deceleration.

Referring to FIG. 9, the control assembly 322 includes a controller 3220, an up key 3222, a down key 3224, a limit switch 3225 and a trigger apparatus 3229. The controller 3220 is electrically connected to the up key 3222, the down key 3224 and the limit switch 3225. The controller 3220 is configured to control the motor 3200. The up key 3222, the down key 3224 and the limit switch 3225 are all configured to control the controller 3220. The trigger apparatus 3229 is configured to trigger the limit switch 3225.

The trigger apparatus 3229 is a plate-shaped structure. The trigger apparatus 3229 is installed on the sliding member body 210 and the trigger apparatus 3229 and the slider 312 are located on a same side of the sliding member body 210. The limit switch 3225 is installed on the vertical beams 1206. The limit switch 3225 is located above or below the trigger apparatus 3229. The up key 3222 and the down key 3224 are both installed on the roof beam 1204. The controller 3220 is installed on an upper surface of the installation plate 1200. The up key 3222, the down key 3224 and the limit switch 3225 are all electrically connected to the controller 3220 by using a wire harness (not shown in the figure). The wire harness is disposed inside the wiring groove structure and is connected to the controller 3220 through the wiring port.

The controller 3220 includes a driver (not shown in the figure) and an elevating control plate (not shown in the figure). The elevating control plate is connected to the driver. The driver is connected to the motor 3200. The driver is configured to control the motor 3200, for example, control the start/stop, speed, steering of the motor 3200. The up key 3222, the down key 3224, an upper limit switch 3226 and a lower limit switch 3228 are all electrically connected to the elevating control plate. The up key 3222, the down key 3224, the upper limit switch 3226 and the lower limit switch 3228 are all configured to control the elevating control plate.

When the up key 3222 is triggered, the controller 3220 is configured to control the motor 3200 to rotate in the first rotational direction. When the down key 3222 is triggered, the controller 3220 is configured to control the motor 3200 to rotate in the second rotational direction. When the up key 3222 and the down key 3224 are simultaneously triggered, the controller 3220 is configured to control the motor 3200 to stop rotating. It should be noted that, because the up key 3222 and the down key 3224 need to be set together for easy operation, there is a possibility of misoperation. When the up key 3222 and the down key 3224 are simultaneously triggered, the controller 3220 is configured to control the motor 3200 to stop rotating, which can prevent the motor 3200 from being damaged by short circuit.

When the limit switch 3225 is triggered, the controller 3220 is configured to control the motor 3200 to stop rotating and control the motor 3200 to rotate only in a preset direction, so that the trigger apparatus 3229 is away from the limit switch 3225.

It can be understood that, there may be one or two limit switches 3225. In this embodiment, the limit switch 3225 includes an upper limit switch 3226 and a lower limit switch 3228. The upper limit switch 3226 and the lower limit switch 3228 are both installed on a same side of the vertical beam 1206. The upper limit switch 3226 is located above the trigger apparatus 3229 and the lower limit switch 3228 is located below the trigger apparatus 3228.

When the upper limit switch 3226 is triggered, the controller 3220 is configured to control the motor 3200 to stop rotating and control the motor 3200 to rotate only in the second rotational direction. When the lower limit switch 3228 is triggered, the controller 3220 is configured to control the motor 3200 to stop rotating and control the motor to rotate only in the first rotational direction. It should be noted that, by setting the upper limit switch 3226 and the lower limit switch 3228, the location adjusting apparatus 20 is automatically prevented from exceeding the maximum stroke without manual intervention, and the motor 3200 is set to rotate in a specified direction to prevent the motor 3200 from being damaged by short circuit caused by misoperation.

The controller 3220 is further configured to control the rate of the motor 3200 increasing from 0 linear or non-linear to a preset value at the moment when the motor 3200 starts to rotate.

The power supply assembly includes a DC base, a power switch and a power indicator. When the DC base is connected to a power adapter and the power switch is opened, the power indicator emits preset light, such as red light, and the controller 3220 and the motor 3200 may work.

Referring to FIG. 10, the second driving mechanism 33 is a manual driving mechanism. The second driving mechanism 33 includes a first helical gear 330, a second helical gear 332 and an elevating hand wheel 334. A connecting rod (not shown in the figure) of the elevating hand wheel 334 passes through the roof beam 1204 and is received in the first shaft base 3100. The first helical gear 330 and the second helical gear 332 are both located in the first shaft base 3100. The first helical gear 330 is fixedly installed on the elevating screw rod 31 and the first helical gear 330 and the elevating screw rod 31 are coaxially disposed. The second helical gear 332 is fixedly installed on the connecting rod of the elevating hand wheel 334 and the second helical gear 332 and the connecting rod of the elevating hand wheel 334 are coaxially disposed. The first helical gear 330 meshes with the second helical gear 332. A rotational axis of the elevating hand wheel 334 is horizontally disposed. It should be noted that, by setting the second driving mechanism 33, in one aspect, the automobile calibration device 100 may be used normally in a status of lacking of power supply. In another aspect, the first driving mechanism 32 and the second driving mechanism 33 share one transmission mechanism 31, resulting in a compact overall structure. It can be understood that, in some other embodiments, the angle between the rotational axis of the elevating hand wheel 334 and the horizontal plane may be set to any value according to an actual situation.

In this embodiment, the automobile calibration device 100 may implement automatic rising and falling of the location adjusting apparatus 20, the clamping apparatus 40, the sliding apparatus 50 and the scale apparatus 60 by setting the driving mechanism 30, to avoid manual adjustment.

In addition, the transmission mechanism 31 is set as the cooperation between the elevating screw rod 31 and the threaded through hole 2120. In the process of lifting the location adjusting apparatus 20, the location adjusting apparatus 20 may rise and fall gently and the position adjusting apparatus 20 is uneasy to slide.

Moreover, by setting the first driving mechanism 32 and the second driving mechanism 33 to be used in the status of lacking of power supply, the applicability of the automobile calibration device 100 is improved. At the same time, the first driving mechanism 32 and the second driving mechanism 33 share the same transmission mechanism 31, thereby improving the overall compactness of the automobile calibration device 100.

Finally, by dividing the gear teeth area 3208 and the non-gear teeth area 3209 on the assembly surface 3207, the rate of the second gear teeth 3204 is controlled to achieve the purpose of deceleration.

Referring to FIG. 11 and FIG. 12 together, the clamping apparatus 40 includes a fixing block 41, a fixing plate 42 and a tension knob 43. The fixing block 41 is fixedly installed on the fixing plate 42. A receiving cavity 44 is enclosed by the fixing block 41 and the fixing plate 42. The receiving cavity 44 is configured to receive a fixing rod of a calibration apparatus. The tension knob 43 is installed on the fixing block 41. The tension knob 43 may rotate relative to the fixing block 41 to extend inside the receiving cavity 44 and to abut against the fixing rod of the calibration apparatus inserted in the receiving cavity 44.

Referring to FIG. 13, the fixing block 41 includes a fixing block body 410 and a locking spring piece 412 and a magnetic element 414. The fixing block body 410 is fixedly installed on the fixing plate 41 and the receiving cavity 44 is enclosed by the fixing block body 410 and the fixing plate 42. The locking spring piece 412 is located in the receiving cavity 44 and is configured to be pushed by the tension knob 43 to abut against the fixing rod of the calibration apparatus. The magnetic element 414 is fixedly installed on the fixing block body 410. The magnetic element 414 is located in the receiving cavity 44. The magnetic element 414 is configured to absorb the locking spring piece 412, so that the locking spring piece 412 is away from the fixing rod of the calibration apparatus. In this embodiment, there are two magnetic elements 414, which are arranged in a vertical direction. The two magnetic elements 414 are respectively located on two opposite ends of the locking spring piece 412, so that the locking spring piece 412 may be strongly and stably absorbed. It can be understood that, in some other embodiments, the quantity of the magnetic elements 414 may be changed according to an actual demand, provided that there is at least one magnetic element 414.

Referring to FIG. 14 and FIG. 15 together, the fixing block body 410 includes a side wall 4100, a bottom wall 4101 and a connecting wall 4102. The bottom wall 4101 connects the side wall 4100 and the connecting wall 4102. There are two connecting walls 4102, which are connected to two opposite sides of the side wall 4100. Similarly, the two connecting walls 4102 are connected to two opposite sides of the bottom wall 4101. The two connecting walls 4102 and the bottom wall 4101 are fixedly installed on the fixing plate 42. The side wall 4100, the bottom wall 4101, the connecting wall 4102 and the fixing plate 42 jointly enclose the receiving cavity 44.

The side wall 4100 is provided with a groove 4104. The groove 4104 is configured to receive the locking spring piece 412. An inner wall of the groove 4104 is provided with a threaded fixing through hole 4106 and a receiving groove 4108. The fixing through hole 4106 is a threaded hole and is configured to mate with the tension knob 43. The receiving groove 4108 is a blind hole and there are two receiving grooves 4108, which are configured to receive the magnetic elements 414. The two receiving grooves 4108 are arranged in a vertical direction and are respectively located on two sides of the fixing through hole 4106.

One side of the side wall 4100 close to the bottom wall 4101 is perpendicularly connected to the bottom wall 4101, and the other side of the side wall 4100 away from the bottom wall 4101 inclines in a direction away from the receiving cavity 44, so that the other side of the side wall 4100 away from the bottom wall 4101 is at an obtuse angle to the bottom wall 4101. A width B of the other side of the connecting wall 4102 close to the bottom wall 4101 is less than a width A of one side of the connecting wall 4102 away from the bottom wall 4101. That is, a width of a bottom of the receiving cavity 44 is less than a width of a port of the receiving cavity 44, so that the fixing rod of the calibration apparatus can be easily inserted in the receiving cavity 44. When the fixing rod of the calibration apparatus is inserted in the bottom of the receiving cavity 44, the fixing rod of the calibration apparatus is firmly fixed in the receiving cavity 44.

Referring to FIG. 13 again, the fixing plate 42 is a rectangular plate, and may be made of stronger materials, such as a stainless steel material.

The tension knob 43 includes a pushing rod 430 and a knob portion 432. The pushing rod 430 has an external thread and passes through the fixing through hole 4106, so that one end of the pushing rod 430 extends in the receiving cavity 44. The pushing rod 430 mates with the fixing through hole 4106 by threads. The knob portion 432 is cylindrical, is fixedly installed on the other end of the pushing rod 430 and is configured to make it convenient for the user to grip and rotate the tension knob 43.

In this embodiment, there are two the fixing blocks 41 and two tension knobs 43. The two fixing blocks 41 are respectively fixedly installed on the fixing plate 42, are located on a same side of the fixing plate 42, and are arranged in a horizontal direction.

Referring to FIG. 16, when the knob portion 432 is rotated in a counterclockwise direction, the pushing rod 430 moves in a direction away from the locking spring piece 412 and the pushing rod 430 is not in contact with the locking spring piece 412. In this case, the magnetic element 414 absorbs the locking spring piece 412 in a direction away from the fixing plate 42, so that a size of the port of the receiving cavity 44 is increased, to facilitate insertion of the fixing rod 200.

Referring to FIG. 17, when the fixing rod 200 is inserted in the bottom of the receiving cavity 44, the knob portion 432 is rotated in a clockwise direction, and the pushing rod 430 is in contact with the locking spring piece 412 and pushes the locking spring piece 412 to abut against the fixing rod 200, so that the fixing rod 200 is clamped in the receiving cavity 44.

In this embodiment, the locking spring piece 412 is pushed to abut against a clamping-needed apparatus such as the fixing rod 200 by using the tension knob 43. Because the locking spring piece 412 is in surface contact with the clamping-needed apparatus, friction between the locking spring piece 412 and the clamping-needed apparatus is increased, so that the locking spring piece 412 can firmly abut against the clamping-needed apparatus. The assembly accuracy of the locking spring piece 412 and the clamping-needed apparatus is reduced, which is conducive to the quick assembly of the clamping-needed apparatus to the clamping apparatus 40. In addition, the locking spring piece 412 is absorbed in a direction away from the fixing plate 42 by using the magnetic element 414, so that the size of the port of the receiving cavity 44 can be increased to facilitate insertion of the clamping-needed apparatus.

Referring to FIG. 18 to FIG. 20, the sliding apparatus 50 includes a guide rail 51, a sliding assembly 52 and a mounting assembly 53. The guide rail 51 may be fixedly installed on the fixing plate 42 in any suitable manner (for example, the guide rail 51 may be fixedly installed on the fixing plate 42 in a screw connecting manner) and is disposed in a horizontal direction. The sliding assembly may be movably installed on the guide rail 51 and is slidable along the guide rail 51 (alternatively, the sliding assembly 52 is movable in a horizontal direction relative to the guide rail 51). The mounting assembly 53 is fixedly installed on the sliding assembly 52 and may follow the sliding assembly 52 to slide along the guide rail 51.

Specifically, referring to FIG. 21, the guide rail 51 is roughly in a cuboid shape and includes a first surface 510 and a second surface 512 that are perpendicular to each other. The first surface 510 is perpendicular to the plane at which the fixing plate 42 is located. The second surface 512 is parallel to the plane at which the fixing plate 42 is located and faces away from the fixing plate 42. Particularly, in this embodiment, the interior of the guide rail 51 is further provided with a plurality of through holes 514 with a predetermined shape in a horizontal direction and is configured to disperse the stress borne by the interior of the guide rail 51. Also, in a case in which a rigid requirement of the guide rail 51 is met, the weight of the guide rail 51 is reduced. It can be understood that, in some other embodiments, the through holes 514 may also be omitted.

The first surface 510 is provided with a first sliding groove 5100 configured to install the sliding assembly 52. The first sliding groove 5100 extends in a horizontal direction. The cross section of the first sliding groove 5100 is roughly in a “trapezoid shape”. A width of the bottom of the first sliding groove 5100 is less than a width close to the opening, to reduce a friction area between the sliding assembly 52 and the first sliding groove 5100, so that the sliding assembly 52 can slide along the first sliding groove 5100 more smoothly. Further, in this embodiment, the opening of the first sliding groove 5100 is in a “T shape” and is provided with first engagement portions 5102 extending to each other, to limit the sliding assembly 52, reduce the shaking of the sliding assembly 52 and avoid the derailment of the sliding assembly 52.

In addition, the first surface 510 is further provided with a horizontal graduated scale 5104 taking its center as the zero point and extending to two sides. That is, the scale of the horizontal graduated scale 5104 takes the center of the guide rail 51 as the zero point and gradually increases to two sides of the guide rail 51, to facilitate the position locating of the sliding assembly 52. It can be understood that, in some other embodiments, the horizontal graduated scale may also be disposed on the second surface 512, or the horizontal graduated scale 5104 is omitted,

The second surface 512 is provided with a second sliding groove 5120 configured to install the sliding assembly 52. The second sliding groove 5120 is parallel to the first sliding groove 5100. That is, the second sliding groove 5120 also extends in a horizontal direction, so that the sliding assembly 52 is slidable along both the first sliding groove 5100 and the second sliding groove 5120 and further moves in a horizontal direction relative to the guide rail 51. Similarly, in this embodiment, the cross section of the second sliding groove 5120 is also roughly in a “trapezoid shape”. A width of the bottom of the second sliding groove 5120 is less than a width close to the opening, to reduce a friction area between the sliding assembly 52 and the second sliding groove 5120, so that the sliding assembly 52 can slide along the second sliding groove 5120 more smoothly. Further, in this embodiment, the opening of the second sliding groove 5120 is also in a “T shape” and is provided with second engagement portions 5122 extending to each other, to limit the sliding assembly 52, reduce the shaking of the sliding assembly 52 and avoid the derailment of the sliding assembly 52.

In this embodiment, a width of the second surface 512 is greater than a width of the first surface 510. Four second sliding grooves 5120 are included. The four second sliding grooves 5120 are parallel to the second surface 512 at intervals. Each second sliding groove 5120 may be configured to install the sliding assembly 52. It can be understood that, in some other embodiments, there may be more or fewer second sliding grooves 5120 according to an actual demand. For example, the quantity of the second sliding grooves 5120 is reduced to one, two or five, or increased to five. This is not specifically limited in the embodiments of the present invention. In the same way, in some other embodiments, a plurality of first sliding grooves 5100 may also be disposed on the first surface 510.

It can be understood that, in this embodiment, the cross sections of the first sliding groove 5100 and the second sliding groove 5120 are roughly in a “trapezoid shape”. Openings of the first sliding groove 5100 and the second sliding groove 5120 are respectively provided with the first engagement portion 5102 and the second engagement portion 5122, so as to enable the sliding assembly 52 to slide more smoothly and to avoid the derailment of the sliding assembly 52. In some other embodiments, the first sliding groove 5100 and the second sliding groove 5120 may also be set as other suitable structures, such as a strip-shaped groove, or a T-shaped groove.

Specifically, referring to FIG. 22, the sliding assembly 52 includes a plate body 520, a first sliding member 522 and a second sliding member 524. One end of the first sliding member 522 and one end of the second sliding member 524 are respectively installed on the plate body 520. The other end of the first sliding member 522 is movably installed in the first sliding groove 5100 and the first sliding member 522 is slidable along the first sliding groove 5100. The other end of the second sliding member 524 is movably installed in the second sliding groove 5120 and the second sliding member 524 is slidable along the second sliding groove 5120. Therefore, the plate body 520 is slidable along the guide rail 51.

The sliding assembly 52 further includes an installation plate 526 and a guiding shaft 528. One end of the second sliding member 524 is fixedly installed on the installation plate 526. The installation plate 526 is installed on the plate body 520 by using the guiding shaft 528 and is movable along the guiding shaft 528 relative to the plate body 520 (alternatively, the installation plate 526 can be close to or away from the plate body 520 along the guiding shaft 528). Therefore, when the sliding assembly 52 is installed on the guide rail 51 (that is, the first sliding member 522 is installed in the first sliding groove 5100 and the second sliding member 524 is installed in the second sliding groove 5120), a distance between the installation plate 526 and the plate body 520 is adjusted by adjusting the guiding shaft 528, so that an assembly error between the sliding assembly 52 and the guide rail 51 may be adjusted, which enables the sliding assembly 52 to slide on the guide rail 51 more smoothly. Certainly, in actual application, the first sliding member 522 may also be installed on the plate body 520 by using another pair of installation plate 526 and guiding shaft 528. Alternatively, the first sliding member 522 and the second sliding member 524 are both directly fixedly installed on the plate body 520.

The plate body 520 is configured to install the mounting assembly 53 and drive the mounting assembly 53 to slide along the guide rail 51. Specifically, in this embodiment, the plate body 520 is roughly in an “L shape”. The first sliding member 522 is installed on one end of the plate body 520. The second sliding member 524 is installed on the other end of the plate body 520. In the plate body 520, an inner surface of one end where the first sliding member 522 is installed faces the first surface 510. An inner surface of one end where the second sliding member 524 is installed faces the second surface 512. Therefore, the first sliding member 522 can be movably installed in the first sliding groove 5100 and the second sliding member 524 can be movably installed in the second sliding groove 5120. It can be understood that, in this embodiment, the plate body 520 adopting the “L shape” can reduce components of the sliding assembly 52 and reduce costs. In some other embodiments, the shape of the plate body 520 may also not be limited to the “L shape”. For example, the plate body 520 may also be in a flat plate shape. The first sliding member 522 is installed on the plate body 520 by using other components.

One side of the plate body on which the first sliding member 522 is installed is provided with a scale pointer 523. After the sliding assembly 52 is installed on the guide rail 51, the scale pointer 523 is located right above the horizontal graduated scale 5104, so as to calibrate the location of the plate body 520. Optionally, the scale pointer 523 is disposed on a central line of the plate body 520 in a horizontal direction. Certainly, it can be understood that, in some other embodiments, if the horizontal graduated scale 5104 is disposed on the second surface 512, the scale pointer 523 is correspondingly disposed on one side of the plate body 520 where the second sliding member 524 is installed.

Two opposite sides of the plate body 520 are respectively provided with a first installation groove 5201 and a second installation groove 5202 that are configured to install the mounting assembly 53. The first installation groove 5201 and the second installation groove 5202 are aligned in a sliding direction of the plate body 520. In this embodiment, the first installation groove 5201 and the second installation groove 5202 are disposed to improve a bearing capacity of the plate body 520 in a vertical direction, so that the mounting assembly 53 can be fixedly installed on the plate body 520 more firmly. It can be understood that, in some other embodiments, the first installation groove 5201 and the second installation groove 5202 may also be omitted.

Moreover, the sliding assembly 52 further includes a locking member 525 configured to abut against the guide rail 51, so that the plate body 520 is fixed on the guide rail 51. In this embodiment, the side of the plate body 520 on which the first sliding member 522 is installed is further provided with a threaded hole (not shown in the figure) configured to install the locking member 525. Specifically, the locking member 525 may include a knob 5250 and a threaded rod 5252. The knob 5250 is fixed on one end of the threaded rod 5252 and the other end of the threaded rod 5252 may pass through the threaded hole and abut against or be away from the guide rail 51. Specifically, when a user tightens the knob 5250 to make the other end of the threaded rod 5252 abut against the guide rail 51, the plate body 520 may be fixed on the guide rail 51. When the user loosens the knob 5250 to make the other end of the threaded rod 5252 be away from the guide rail 51, the plate body 520 may slide relative to the guide rail 51, which is convenient to readjust the location of the plate body 520. Similarly, it can be understood that, in some other embodiments, the locking member 525 may also be installed on other suitable locations of the plate body 520. For example, the locking member 525 is installed on one side of the plate body 520 where the second sliding member 524 is installed. Moreover, the specific structure of the locking member 525 may also not be limited to the structures described above, provided that the plate body 520 can be fixed or move relative to the guide rail 51.

Two first sliding members 522 are included. The two first sliding members 522 are horizontally disposed along the first sliding groove 5100.
